POWERFUL AND RESPONSIVE

400-SERIES EFI ENGINE

A 397cc single-cylinder 2-stroke engine with 65-class horsepower and electronic fuel injection (EFI) offers quicker, more responsive power that gives you a smoother take off every time.

With an industry-first design that’s compact and lightweight, this EFI engine brings 65-hp and 397cc performance to every ride, all while remaining under 50 lbs. A 3-stage exhaust valve system takes this power to the next level, delivering improved throttle response and better overall engine performance. As a liquid cooled engine, a counter balance shaft eliminates most engine vibration. The result—a lightweight-but-mighty power source that fuels a ride like no other.

ELIMINATES BUMPY RIDES

SLIDE-RAIL REAR SUSPENSION

This responsive rear suspension uses a full 12.5 inches of travel to absorb any bumps on the trail. With support like this, every ride will be so stable and smooth, you won't even notice the rough snow.

ENHANCED MANEUVERABILITY

MID-SIZE CHASSIS

There's nothing better than a snowmobile that's easy to handle. With its lightweight, mid-sized chassis, the Riot 400 gives you more control over your ride, on- or off-trail.

SMOOTH POWER DELIVERY

ARCTIC DRIVE SYSTEM

The durable Arctic Drive System has a CVTech Trailbloc drive clutch and CVTech Invance driven clutch to deliver power to the snow. It also provides more low-end power and throttle control.

PROVEN SUSPENSION

ARCTIC MOUNTAIN SUSPENSION

The Arctic Mountain Suspension (AMS) is built specifically to navigate through deep snow. With lightweight spindles and precision engineered suspension geometry designed with mountain riding in mind, AMS optimizes your performance in deep snow.

BETTER POWDER PERFORMANCE

COBRA TRACK

With a unique lug shape and pattern, this 146-in track with 1.6-in lugs delivers the optimal balance of traction and float in loose snow. This gives you enhanced powder performance while reducing track noise.
